Description
15 20 25 30 35 447 978 Lämpligen har munstycket en rotationssymmetrisk form, och den kupol- formade spetsen har lämpligen en väsentligen halvsfärisk form. Med uttrycket "spets" skall sålunda inte förstås att den främre änden är "spetsig“. I denna text har benämningen spets i stället samma betydelse i exempelvis fingerspets. Preferably, the nozzle has a rotationally symmetrical shape, and the dome-shaped tip suitably has a substantially hemispherical shape. Thus, the term "tip" should not be understood as meaning that the front end is "pointed".
Ytterligare kännetecken på och fördelar med uppfinningen framgår av de efterföljande patentkraven samt av följande beskrivning av en före- dragen utföringsform.Further features and advantages of the invention appear from the following claims and from the following description of a preferred embodiment.
KORT FIGURBESKRIVNING I den följande beskrivningen av en föredragen utföringsform kommer att hänvisas till bifogade ritningsfigurer, av vilka Fig. l utgör en perspektivisk vy som visar munstycket enligt uppfin- ningen snett framifrån, Fig. 2 visar samma munstycke från ena sidan, och Fig. 3 utgör en sektion III-III i Fig. 2.BRIEF DESCRIPTION OF THE DRAWINGS In the following description of a preferred embodiment, reference will be made to the accompanying drawing figures, of which Fig. 1 is a perspective view showing the nozzle according to the invention obliquely from the front, Fig. 2 shows the same nozzle from one side, and Fig. 3 constitutes a section III-III in Fig. 2.
BESKRIVNING AV EN FÖREDRAGEN UTFÖRINGSFORM Det i figurerna visade munstycket består av en rörformig hylsa 1 av mässing med en trubbig, halvsfärisk spets 2 med jämn yta. Hylsan 1 är rotationssymmetrísk. En ledning 3 för het luft kan anslutas till hylsans 1 bakre ände. För att underlätta på- och avförandet på ledningen 3 är anordnad en greppfläns 4.DESCRIPTION OF A PREFERRED EMBODIMENT The nozzle shown in the figures consists of a tubular sleeve 1 of brass with a blunt, hemispherical tip 2 with a smooth surface. Sleeve 1 is rotationally symmetrical. A hot air line 3 can be connected to the rear end of the sleeve 1. To facilitate the loading and unloading on the line 3, a gripping flange 4 is arranged.
Genom hylsans l cylindriska del 5 sträcker sig två munstycksöppningar 6, 7 snett framåt, för att mynna omedelbart bakom det halvsfäriskt formade partiet. Det axiella avståndet från spetsens 2 centrum och öppningarnas 6 och 7 främre ände uppgår till mellan 4 och lO mm beroende på munstyckets övriga dimensioner. Genom öppningarna 6 och 7 kan den heta luften riktas mot skarvstället, även då man arbetar i vinklar och hörn. Genom att några öppningar inte är anordnade åt andra håll, det vill säga i tvärriktningen i förhållande till öppningarnas 6 10 15 20 25 30 35 447 978 och 7 diametralplan, så undviker man samtidigt att plastmattorna på sidan om skarven upphettas och skadas. Man riktar med andra ord varmluften endast mot de områden där den behövs.Through the cylindrical part 5 of the sleeve 1, two nozzle openings 6, 7 extend obliquely forward, to open immediately behind the hemispherically shaped portion. The axial distance from the center of the tip 2 and the front end of the openings 6 and 7 amounts to between 4 and 10 mm depending on the other dimensions of the nozzle. Through the openings 6 and 7, the hot air can be directed towards the joint, even when working at angles and corners. Because no openings are arranged in other directions, i.e. in the transverse direction in relation to the diametrical planes of the openings 6 7 15 15 25 25 35 35 447 978 and 7, the plastic mats on the side of the joint are simultaneously heated and damaged. In other words, the hot air is directed only at the areas where it is needed.
Godset i spetsens 2 centrala del 8 är tunnare än i rörpartiet 5. En lämplig tjocklek är 1-2 mm. Vid grövre godstjocklekar måste luft- temperaturen ökas för att spetsen 2 skall bli tillräckligt varm. Detta kan emellertid orsaka att varmluften skadar ikringliggande plast.The goods in the central part 8 of the tip 2 are thinner than in the pipe section 5. A suitable thickness is 1-2 mm. For coarser wall thicknesses, the air temperature must be increased for the tip 2 to be sufficiently warm. However, this can cause the hot air to damage the surrounding plastic.
Dessutom kan kvarvarande plastrester på spetsen brännas då man växlar objekt.In addition, residual plastic residue on the tip can be burned when changing objects.
Munstycket kan givetvis modifieras inom uppfinningstankens ram.The nozzle can of course be modified within the scope of the inventive idea.
Sålunda är det inte nödvändigt att munstycket är helt rakt. Man kan sålunda mycket väl tänka sig att den rörformiga delen är krökt för att ytterligare underlätta arbetet i svåråtkomliga hörn och skrymslen.Thus, it is not necessary that the nozzle be completely straight. It is thus conceivable that the tubular part is curved to further facilitate the work in hard-to-reach corners and nooks and crannies.
